COIN-CONTROLLED BICYCLE-PUMP.

SPECIFICATION forming part of Letters Patent No. 626,268, dated June 6, 1899.

Application filed September 21, 1898. Serial No. 691,492. (No model.)

. the mechanism of coin-controlled bicyclepumps, and comprises the novel features hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of my device. Fig. 2 is an elevation taken at right angles to Fig. 1. Fig.3 is a section taken through a portion of the casing, showing the means used for locking the crank-shaft. Fig. i is a sec tional elevation of the lower portion of the casing, other parts being shown connected therewith. Fig. 5 is a similar view showing the parts in a different position. Fig. 6 is a partly-sectional elevation of details, taken upon the line 6 6 of Fig. 4; and Fig. 7 is a similar section taken on the line 7 f Fig. 5 and showing the same parts in different position.

The object of my device is to provide means by which a mechanism for inflating a bicycle or other pneumatic tire may be released by the insertion of a coin, and thus permit the tire to be inflated. It comprises apump which normally is locked, so that it cannot be operated, and means by which the pump-operating means may be released by the insertion of a coin.

The operating and controlling mechanism of my device is included within a casing A, which is of any suitable form. J ournaled in this casing at a convenient height for rotation is a shaft 13, which has upon one end a fly-wheel B, provided with a crank by which it may be turned, and upon the other end a crank-disk B Upon the base of the casing is mounted a pump D, which is of any suitable form and has the pump piston-rod G extending upward along one face of the casing and sliding within guide a. This pump piston-rodis connected with the crank-disk by means of a rod 0, which at its upper end is pivoted to the rod 0 and at its lower end is pivoted upon a crank-pin Z), carried by the crank-disk B The crank-disk B occupies an opening in one face of the casing and'has a series of pins 1) projecting from its inner face. Mounted upon the casing beneath the disk 13 is a locking-lever F, which is pivoted so that its upper end may be inserted between adjacent pins 1) upon the disk, and thuslock it against rotation. This is the normal position of the locking bar or lever F.

Pivoted upon a shaft E, which is journalcd in the casing beneath the lever F, is a hook E, which is provided at its inner or pivot end with a segment E This is also provided with two projections e and 6 so placed as to engage the lower end of the lever F when the hook E is swung to its limit in either direction. This hook E swings through a slot A in the casing and when in its upper position forces the lower end of the lever F back by engagement therewith of the lug or projection 6'. This holds the upper end of the lever between the pins (2 upon the crank-disk, and thus prevents its rotation. \Vhen the hook E is thrown down to the horizontal position, as is shown in Fig. 4, the lug or projection e engages the opposite side of the le ver F and throws its upper end out of engagement with the pins 12. The segment E upon this hook is also provided with a notch adapted to receive one end of a lockinglever H. The other end of this lever II projects into a slot 9, formed in one side of the coin-chute Gr. The end of this lever is so placed that the coin which passes down through the chute cannot pass the lever without forcing this end downward, and thus elevating the opposite end sufliciently to free it from the slot 6. Normally the hook E is in the elevated position shown by full lines in Fig. 5, and consequently the pump-operating mechanism is locked, so that the pump cannot be operated. When a coin is inserted in the chute, it will engage the lever 11 and free the hook E, so that it may be thrown down into engagement with the upper side of the wheel-rim, as shown in the drawings.

To properly locate the wheel, a notched plate a is provided, adapted to receive the lower side of the wheel, and a hook a is secured to the frame where it will engage the upper portion of the wheel, and thus hold it steadily. lVhen the bicycle has been placed in this position, the tire-nipple may be con nected with the pump through the hose cl, which is permanently connected to the pumpoutlet.

The under surface of the hook E is engaged by a fiat spring I, which prevents its dropping down unless engaged bythe hand. The shaft E, upon which the hook E is mounted, extends outside the casing and has a handle E secured thereto, by means of which it may be operated.

The operation of my device is as follows: The bicycle-wheel K is placed in the hooks a, and a provided therefor. The coin is then placed in the coin-chute. This releases the locking-hook E and enables it to be thrown downward, so as to engage and hold the Wheel. When it reaches its lowest position, the crankdisk is released and the pump may be operated. When the hook E is thrown upward, it forces the leverF into engagement with the pins on the crank-disk and looks it against rotation, at the same time causing one end of the lever H to drop into the notch e, and thus to lock the hook E in its upper position. To release it, theinsertion of a second coin is required.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A coin-controlled bicycle-pump, comprising a casing, a pump and its operating mechanism within the casing, said mechanism including a rotating disk having a series of projections thereon, a power-crank external the casing and connected with the pump-operating mechanism, a locking-lever adapted to normally lie between adjacent projections on the disk to lock it, and coin-controlled means for releasing the lever from the disk, substantially as described.

2. The combination of a pump and operating means therefor, including a rotating disk having a series of projections to prevent op eration of the pump, a movable hook adapted to engage and hold the bicycle and also to engage the locking-lever to shift it, and a coincontrolled lever normally having locking en gagement with the hook and released therefrom by the insertion of a coin, substantially as described.

3. Acoin-controlledbicycle-pump,comprising a pump, a crank-shaft, a crank-disk on the shaft having a series of locking projecpiston, a locking-lever normally engaging the projections on the disk, a hook adapted to engage and lock the bicycle-wheel, means by which said hook may control the crank-disklocking lever, a locking-lever engaging said hook, and a coin-chute directing the coin upon said lever and thereby releasing the hook,

substantially as described.

4. A coin-controlled bicycle=pum p, comprising a pumping mechanism, a lock therefor, a hook-adapted to engage and hold the wheel and having controlling connection with the pump-locking mechanism, said hook having a notched segment attached, a catch adapted to drop into the notch in said segment, and a coin-chute having one end of the catch projecting into it, whereby the catch is engaged by a coin and freed from the hook, substantially as described.

5. A coin-controlled bicycle-pump, comprising a pump, a crank shaft having a disk thereon provided with looking projections, and operative connections with the pump, a pivoted hook adapted to engage the bicyclewheel and having a locking-notch, a pivoted catch normally engaging said notch, a coinchute having a slot receiving one end of the catch, whereby the coin may engage the catch and free it from the hook, and a pivoted lever engaging by one end the projections on the crank-disk and engaged at its other end by the hook, substantially as described.

6. The combination of a pump and operating means therefor, with a locking-lever normally engaging and locking the operating means, a movable hook adapted to engage and hold the bicycle and also to engage the locking-lever to shift it, and a coin-controlled lever normally having locking engagement with the hook and released therefrom by the insertion of a coin, substantially as described.

7. The combination of a pump and operating means therefor, a lock engaging said operatin g means to prevent their use, a movable hook adapted to engage and hold the bicyclewheel and also to control the lock for the adapted to-be released by the insertion of a coin, substantially as described.
